STOPPlNG MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 308,311, dated November 18, 1884-.

Application filed October 1, 1883. (No model.)

shaft with an additional arm, which acts to effect the shifting of the belt onto the loose pulley before the other arm of the protectorshaft comes in contact with the stop on the breast-beam, so that the momentum only of the lay has to be arrested, there being no application of power thereto when the stop acts.

I11 the accompanying drawings, Figure 1, Sheet 1, is a side view of suflicient of a loom to illustrate our invention; Fig. 2, Sheet 2, a view looking in the direction of the arrow 1, Fig. 1, the lay being omitted; and Fig. 3, Sheet 3, a plan view of part of Fig. 1.

A A represent part of the side frames of the loom, having bearings for the end drivingshaft, B, and for the crank-shaft D, the latter being connected to the lay E, and being driven from the shaft B by spur and bevel gearing in the usual manner. (See dotted lines, Fig. 1.) The shaft B has fast and loose pulleys a a for receiving a belt from any adjacent countershaft, the belt being shifted from one pulley to the other by a fork, I), on a rod, (1, guided in a bracket, 0, on the frame A, and acted on to bearings on the breast-beam and frames of object we attain by providing the protectorby a spring, f, which tends to draw the rodthe loom, and is at liberty to move longitudinally and also to turn in said bearings. The upper or short arm of the lever G has a lug, m, which is adapted to engage wiih a lug, m, on a lever, H, hung to a pin, 0, on the frame A, a spring, o. tending to move the lever H in the direction of the arrow, Fig. 3, and thus retain the lug m of the lever H in engagement with the lug m of the lever G, the driving-belt being under such circumstances upon the fast pulley a. When the lever H is moved in a direction contrary to that pointed out by the arrow, however. so as tofree the lever Gfrom the control of the lug m, the spring f causes the retraction of the rod d and the shifting of the belt from the fast to the loose pulley. This shifting of the belt must take place whenever a shuttle fails to properly enter the box; hence the lay E carries a protector mechanism, which, as usually constructed, consists of a rock-shaft, t, extending across the lay. and having arms a and 1), one arm n, being arranged near each end of the shaft. and each of said arms it having a lug. 8, adapted to bear upon a shuttle-binder, la, in the front of one of the shuttle-boxes, so that when the shuttle enters the box the binder 70 will press the arm a outward and depress the armp, as shown by full lines in Fig. 1, the arm remaining in the elevated position shown by dotted lines when the shuttle fails to properly enter the box. One end of the shaftt' and one arm, a, only are shown in the drawings. When in the position shown by dotted lines, the armp on the forward movement of the lay strikes a stop on the breast-beam and prevents the lay from beating up, otherwise the shuttle remaining in the shed would break the warp-threads. In the usual construction the arm 19 has also been caused to effect the sl'iii'ting of the belt from the fast to the loose pulley, said arm striking a lever, which presses the shippero handle out of its notch and causes the necessary movement of the belt just before the movement of the lay is arrested by contact of the arm with the stop or hunter. The obj eotion to this plan is that the operations follow 5 each other so closely that the belt cannot be fully shifted before the contact of the arm with the stop; hence the forward movement of the lay is arrested while power is still being applied to cause such movement, and in consequence sudden shocks and a severe straining of the loom result. XVe overcome this objection by providing the protector-shaft i with an additional arm, .1, which acts in advance of the stop-arm 1), so that ample time is afforded for fully shifting the belt before the movement of the lay is arrested. The arm a: has a canrlike outer end adapted to strike the downwardly-bent end of the lever H, and cause the vibration of said lever, so as to withdraw its lug m from engagement with the lug m of the lever G. 'A lever, J, is hung to the lever G, and a lever, J, to an arm, i on the shaft 71 the short arms of the lever being adapted to slots in the frame A, so that by manipulating either of the levers a longitudinal movement of the shaft h against the action of a spring, h, maybe effected, this movement being suflicient to free the lug in of the lever G from engagement with the lug m of the lever H, the latter being retained by contact with a stop, '0, on the frame. The

loom can thus be thrown out of gear by hand from either side, or the release of the lever G may be effect-ed by operating the lever H by hand.

\Ve claim as our invention I 11 The combination of the lever G and the belt-shifting devices of the loom connected to said lever, the lay E, the shuttle-boxes, the breast-beam, thelever H having a lug adapted to engage with and retain the lever G, and the protector-shaft having a stop-arm, p, and an arm, 41*, adapted to strike and cause the vibra' tion of the lever H, as set forth.

2. The combination of the lever G, the arm 3 the shaft h, the spring h, the levers J J, the slotted frame A A, and the lever H, as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
